VENTILATING BULK-WINDOWS, STORES, 80C.

SPECIFICATION forming part of Letters Patent No 341,318, dated May 4, 1886.

Application filed January 2, 1886. SeIia T70. 187,471. (No model.)

To all whom it may concern:

Be it known that I, T. Tnnonon COHEN, of Philadelphia, Pennsylvania, have invented and produced a new Improvement for the Ventilation of Bulk-VVindows, Stores, Offices, or Dwelling-Houses, of which Iannex drawings and full description.

This invention relates to devices for ventilating bulk-windows, stores, offices, and'other apartments; audit consists in novel means for hanging a shutter or valve above the window glass or sash, as will be fully understood from the following description, when taken in connection with the annexed drawings, in which Figure l is an inside elevation of a windowframe and window having my improved ventilator applied to the same and closed. Fig. 2 is a similar view of the same parts, showing the ventilator open. Fig. 3 is'a vertical central section through Fig. 1. Fig. 4 is a similar view of Fig. 2. Fig. 5 is an inside view of one of the end pivotal holders for the Von tilator-plate. Figs. 6 and 7 are front and top views, respectively, of one of the said holders. Fig. 8 shows one of the slotted bearing-plates for the pivots of the holders. Fig. 9 shows an adjusting-rod and its thumb-screw, and Fig. 10 is a view of the perforated plate h.

In the annexed drawings, A designates a window-frame, in which is applied the window-plate 13,-above which is my improved ventilator, which is constructed in the following manner: 0 designates a window-plate, which, with its 'end holders, is designed to close the space left between the upper edge of the plate B and the lintel of the windowframe A, as shown. The holders D D for the plate 0 consist of side wings, I) 1), formed on which are gudgeons or pivots b, the narrow ertical angular portions b, and angular lips stirrups 12 which latter support the ventilator-plate O, as shown in Figs. 3 and 4. In front of the plate 0, and secured by screws e e to the wings I) b, are plates F, having flanges 0, between which and the angular portions If of the said wings grooves (Z are left, in which the ends of the ventilatorplate O are received and confined. The gudgeons or pivots b of the holders D D are supported in bearingplates Is, rigidly secu red to the inner sides of the uprights of the window-frame A, and c0nstructed with slots Z, which readily allow the application and. removal of the ventilator.

From the upper angle of one of the plates Z) projects an arm, b, to which is suitably attached a rod, G, adapted to be secured to a perforated screw-tapped plate, h, by means of a thumbscrew, g.

It will be seen from the above description thatI employ a narrow glass section, 0, above the upper terminus of the windowplate O, which section can be vibrated on its end bearings and secured by the screw 9 at any desired angle, according to the size of the opening re- 6 quired for ventilation. It will also be observed that the ventilator-plate O can be readily removed from and applied to its 1101C1813Sg also, that I provide ,a strip, a, of rubber or other suitable packing across the top of the glass, to prevent the entrance of water while washing the same from the outside.

Having described my invention, I claim- 1. The holders D D, each composed of a wing, Z), provided with angular flanges Z) Z), 5

and a pivot, b, in combination with an angularly-flanged portion, F, forming a groove, d, for receiving the ventilatorplate O, substantially as described.

2. The combination, with a window having a ventilating-space above its plate B, of a vibrating ventilator pivoted and mounted as described, a packing, a, an arm, I)", on one of the holders, an actuating-rod connected to said arm and provided with a thumbscrew, 8
